The White v. Walmart AI lawsuit is an ongoing employment case in the U.S. District Court for the Southern District of Indiana in which Magistrate Judge Tim A. Baker publicly rebuked plaintiff’s attorney Mark Waterfill for uploading Walmart’s discovery responses into an AI tool, copying the program’s list of alleged deficiencies, and forwarding it to opposing counsel and the court without checking whether any of the flagged problems actually mattered. On April 14, 2026, Judge Baker called the approach a “perilous shortcut” and set out expectations for how attorneys may use AI in discovery, stopping short of formal sanctions but warning that copying AI output is not the same as practicing law.
What the Underlying Lawsuit Is About
Cynthia White sued Walmart, Inc. on June 8, 2025, alleging wrongful termination and retaliation after she reported a workplace injury and filed a worker’s compensation claim. The case, docketed as No. 1:25-cv-01120-RLY-TAB, was assigned to Judge Richard L. Young with a referral to Magistrate Judge Baker. White demanded a jury trial.
The merits of White’s claims have not been decided. From the beginning, the case has been stuck in discovery. Walmart served interrogatories and document requests in July 2025, White’s initial responses the following month were incomplete, her original attorney withdrew, and Waterfill later appeared on her behalf. By early 2026, White still had not provided signed interrogatory answers or identified her medical providers, and each side was accusing the other of inadequate responses.
What the Attorney Actually Did With AI
A conference call scheduled for March 23, 2026, to resolve the discovery impasse fell apart when Waterfill declined the invitation without explanation. Judge Baker then held a formal discovery conference on April 10, 2026, and that is where the AI conduct came out.
Rather than reading Walmart’s discovery responses himself and identifying real problems, Waterfill had fed them into an AI program and asked it to flag deficiencies. The AI flagged every single one of Walmart’s interrogatory answers. Waterfill copied that output into an email, sent it to opposing counsel and to the court, and presented it as his analysis. He acknowledged he had not independently reviewed whether any of the AI-identified issues were material or worth raising.
Judge Baker described this as sending an “electronic ultimatum” instead of engaging in the good-faith conferral that the federal discovery rules require. The judge found that Waterfill “ceded his professional judgment to AI” and that his “exclusive reliance on AI-generated discovery responses” did not satisfy his obligation to meet and confer with the other side before dragging a dispute in front of the court.
What Judge Baker Ordered
The written order issued April 14, 2026, did not impose fines or formal discipline. Judge Baker acknowledged that AI platforms can be “useful discovery tool[s]” and that their use is “not itself problematic.” The problem, he wrote, was the absence of any human filter between the machine’s output and the court filing.
The order laid out three expectations for attorneys using AI in discovery:
- Parties “must vet any factual and legal references generated by AI” before using them in court.
- Before raising a discovery dispute, an attorney must “independently consider any discovery deficiencies identified by AI” and decide whether they are significant enough to pursue.
- Pasting AI output into an email to opposing counsel does not amount to the substantive back-and-forth negotiation the rules require before a judge is asked to intervene.
Judge Baker’s summary line drew national attention: “AI is a useful tool, but not a substitute for good lawyering.”1Reuters.

Why This Ruling Is Different From the Other AI Cases
Most of the AI-in-court headlines over the past few years have involved hallucinated citations. In June 2023, Judge P. Kevin Castel of the Southern District of New York sanctioned two attorneys $5,000 in Mata v. Avianca, Inc. for filing a brief with six fictitious opinions generated by ChatGPT.5Justia. Mata v.

Waterfill’s conduct in White v. Walmart was a different problem. He did not file fake cases. He submitted a real but unfiltered machine-generated critique and asked the court and opposing counsel to treat it as his own considered analysis. Judge Baker’s order targeted that specific behavior: the delegation of judgment itself, not just the risk of fabricated authority. For any lawyer using AI in discovery, the ruling sets a straightforward rule. Read what the AI produces, decide what actually matters, and do not send anything to opposing counsel or the court until a human has made that call.
